Human Activity-Optimized CRISPR Knockout Library (3 sub-libraries in lentiCRISPRv1)
(Pooled Library #1000000100)

  • Purpose

    The Sabatini/Lander CRISPR pooled library is optimized for cleavage activity, in order to maximize the likelihood of gene knockout.

    The library is split into three sub-libraries. Two tubes each contain 90,000 gRNAs each or 5 sgRNAs per gene. The third tube contains 5,000 gRNAs.

  • Vector Backbone

    lentiCRISPR v1- Note: This plasmid has been discontinued, as an updated version is available. For confirmation of screen hits, Addgene encourages users to use the updated lentiCRISPR v2, which can be requested separately.

Library Shipping

This library will be delivered as three pooled DNA sub-libraries in microcentrifuge tubes on blue ice. The tubes' contents will not necessarily be frozen. For best results, minimize freeze-thaw cycles.

Note that each subpool must be transformed separately.

You will receive two sub-libraries with 90,000 gRNAs each at

  • Volume
    ∼15 µL
  • Concentration
    10 ng/µL

You will additionally receive one sub-library (hL3C9) with 5,000 gRNAs each at

  • Volume
    ∼20 µL
  • Concentration
    20 ng/µL

Depositor Comments

The depositing lab notes that the DNA preps should be performed separately and then mixed together during virus production at ratios consistent with the pool size.
